Do you have an amplifier with a (sometimes) buzzing toroidal transformer? This DC trap or DC filter removes or at least lowers the buzzing.

Interesting features:

1. Room for up to 6 x 68000 uF snap-in high performance caps.
2. Four DC blocking voltages.
3. Very thick copper traces, virtually impossible to burn off.
4. Gold plated pads.
